Nope! If you have a Talkshoe account, you're more likely to get on the air, though, but it's not required at all. When you call into the show's phone number, you have the option to call in as a guest caller. When you connect to the show's web site during a show, you'll also have the option of joining the live show chat room as a guest as well.

The reason why you're more likely to get on the air as a TalkShoe account is that guests can sometimes show up to wreck shows. In our other podcast, the Black Rock Lost Podcast program, we had once had a guest log in and began speaking lewdly. I thought it was hilarious because the person was self-censoring his own swears.. but it was a lesson in defaulting to muting guests.
